Application filed May 28, 1910. Serial No. 563,957. 1

'To all whomit may concern:

Be it known that I, VILLIAM F. MCGLIN- new, a citizen of the UnitedStates, resid-- ingat Cincinnati, in the county of Hamilton and State ofOhio, have invented certainnew and useful Improvements inCarpebSweepers, of which the following is a specification.

The object; of my invention is to provide a. more simply constructed andmore efliciently operatingrunning gear and brush- ;hjvingmechanisni fora carpet sweeper,

' andto provide means for adjusting the;

Jarush tothework and for removahly mount ing the brush in the sweeper ina moreslmpleand etlicient manner.

- My invention; .consistsin the combination inga sweeper of the 'type inwhich the brushis .rota ted.by direct contact with the periph-ilevertogether-with novel means for adjust-'- ably applying said wheelsto said brush; as

cries of the wheels of the sweeper, of a -bnush adjnsting. mechanismcomprising a:

well as in the other details of construction and arrangement as willhereinafter be more fully described and claimed.

In the drawing: Figure 1 is a plan view of one end of a sweeperembodying my in vention. liiggfl is an end view of the same showingthcileverin position for releasing thebtush-from the sweeper.

The casing 1 has a flat top 1 and sloping sides 1" as is usual 'in theconstruction of sweepers Of-tlllSClltlIilCtOI. This casing also sides1",

basin-set ends. which, together with said flat 'top l, sloping sides 1,and verticah incloses a space inside the "j sweeper the bottom ofwhich'is formedby' pans 1"-liinged at 1" and tilted by any well knownoperating device such as the pu'sh- IOdHl and normally heldclosedby thespring -1.". Lying within the casing-and extendingdownward through aspace .be-. tween .thepans 1 is the brush 2, This brush 2 extendsoutside the casing through tween-1 said.- tmountmgsx and slots 1*" inthe in-set ends 1 at both ends of the sweeper, and. is provided withpulleys 2 to be engaged by the wheels 3 which havol tires-3' of rubberor similar material to make effective frictional contact with the.pulleys 2. of the brush-and rotate the brush when the wheels rolloverthe floor or other surface to b'e swept;

The foregoing. de'scriptioiisets forth details' common to carpetsweepers heretofore disclosed, b'ut it.is.- in thedetails 'andvin thearrangement ofid'tails', in combination with the foregoing" details;..as hereinafter described; that my invention-i consists.

The, lower end'ot the slot 4 in the mounting .4 isalso-opem'andtlie lever 5 and its extension and-the slot' 5" therein areso proportioned thatttlTe' open end of the slot '5" may coincide witlithe open end of the slot 4-in.sueh a manner" as to: allow the spindle 2'of the'brush 2 to escape. from said slots, as-is bestsh'owlrin'-Fig.'2of'tlte drawmg. The lever 5 has another extension 5 lever 5 only duringthe process of inserting and removing the brush from the sweeper.

by the means above set forth.

The lower part of theslot 6 is widened and is provided with a series ofprojections 6", while the part of the lever 5 adapted to ass along thispart. of the recess 6 has a ongitudinal slot 5", which may receive anyone of the projections 6" in the widened part of the recess 6' in theplate 6, thereby holding the lever 5 stationary in various adjustedpositions and providing a corresponding number of adjusted positions ofthe brush for operation in the sweeper. V

The part of the lever 5 comprised by the extension 5 is made resilientsothat it will spring in and automatically admit the'pro jections (3into its slots 5, as the lever is brought in the region of saidprojections.

From the foregoing description it will be seen that to insert the brushinto the'sweeper it is only necessary to bring the lever 5 up until theopen ends of the slots5 and 4* coincide, then slip the brush into thesweeper, passing the spindle 2 of the brush through the coincidingopenends of said slots and bear inwardly of the sweeper on the brush, thusbringing the extensions of the levers upward and inward, and bringingthe extensions 5 downward and outward until the slots 5" therein admitthe first projections (3 of the plates 6, whereupon the brush is heldpositively in position-for operation. Then if it be desired to-adjustthe brush farther up in the sweeper the adjustment may bc'accomplishedbypressing the extension 5" outward, releasing the lever and bringing itso that the desired projection ti enters the slot of the lever. When thelevers have been brought down to hold ,the brush in operating positionthey will lie below the surface of the fiat top 1 of the casing and thusbe out of position to engage with any objects under which the.

sweeper is passed in sweeping, such as chairs and other articles offurnlture, so

that the marring of such articles by the en gagement of these levers isavoided. This position of the lever is best illustrated in Fig. 3 of thedrawing.

W' hen the brush 2 is adjusted up and down with its pulley 2 lyingbetween the wheels 3, it is necessary that the wheels be allowed to bedisplaced in a general horizontal direction, moving inward toward eachother when the brush is lowered, and moving outward away from each otherwhen the brush is raised, as will be seen upon inspection of thedrawing. To mount the wheels in the sweeper in a simple manner to allowsuch horizontal displacement and at the same time maintain the wheels incontact with the pulley 2 at all times and at alladjustments, I providebrackets? for said wheels which brackets comprise arms '4' havingpivotal connections 7*" with tl1e-in-set ends 1* of thecasing near thetop of the sweeper and extending down-' ward and provided at their lowerends with horizontal outwardly extending spindles 'l" on whichthewheels, are rotatably mounted.

the engagement against their outer sides of the mountings 4 that extendacross the ends of the sweeper, said mountings having lugs t with smoothinner faces to engage with may swing on their pivotal connections 7 andcarry the wheels on the spindles 7" outreat radius --to constitute asubstantially resist the outward movement of the wheels as carried onthe arms 7 springs 7 are provided. Each of these springs consists in apart fixed to the in-set end 1 of the casing and extending upwardforming a loop, and

pivotally attached to the spindle 7" immediately adjacent to the arm 7*.

For forming a guide for the arm 7" its to, a plate 8 is secured to thein-set end 1 of the casing by lugs 8' that extend inward, whereby saidplate 8 is separated a short distance from the in-set end, leaving .aspace between it and said end. This late '8 has a horizontal slot 8, andthe spin le 7 of the wheel 3 extends through this slot to receive thewheel 3, which wheel bears inwardly against the outer side of the plate8. Thus -the spindle 7 may swing inward and outjward with the arm 7along this slot 8 in the plate 8, and the wheel bearing thereagainst mayslide 'therealong during such displacement. This plate is comparativelythin, and while serving the pur oses of a guide and a bearing for thewhee also serves to interrupt such ravelings as arev taken up by thewheel, the ravelings passing inside the plate and down through thespacebetween it and the in-set end 1", being thus separated from the wheeland their accumulation on the wheel and the spindle avoided, so that.the clogging and excessive wear on the parts ordinarily caused by theaccumulation of such ravelings are eliminated.

' The mounting 4 has an outwardly projecting boss 4: with a recess 4 inits upper side, and an outwardly projecting lug 4 is located immediatelyabove this recess. The bail 9 Said wheels 'are held on these spindles bythe hubs of the wheels Thus the arms 7- horizontal displacement of thewheels. To

ward or inward along an arc of sufficiently.

then extending downward with another part spindle 7 b and the spring 7attached there- I 4 has an eye 9'" that fits onto the lug 4 and lies inthe recess 4" in the boss at", the sides of said recess 4" being made toconform to the'eye 9 of the bail 9, so that when the bail pivots on thelug 4 it will also turn closely against the sidebithe recess, wherebythe boss 4" may constitute a reinforcement. of the lug 4 as anattachmentof the bail to the sweeper. Preferably an opening 4" isprovided in the lower side of the recess 4" to permit-the escape andprevent the accumulation of obstructing 'matter in the recess around theeye of the bail, and a plate4 maybe riveted onto the boss P extending uppast the eve of the bail-to hold the bail in place. This boss 4' and theother parts associated therewith for the attachmentof the bail, aremounted immediately outside the slot 4 in the mountin 4, so that theattachment ofthe bail isc losely adjacent to the bearing of the brush inthe sweeper. Thus the propelling power at the sweeper is appliedtheretoat the mostetfective- P int to he applied directly to the brushand avoid the tendency to the-tilting of the sweeper, as is the case ifthe bail be attached to'the sweeper at a point considerably above thebearing of the brush.

In the combination of a simple mechanism allowing a perfectverticatadjustinent of the brush in the sweeper thus maintaining thebrush in its position in the middle of the sweeper. and maintaining thedistance between the brush and the two pans equal at all adjustments,and effecting such vertical adjustment with the use of a lever having asimple means for holding it positively in its various adjustedposit-ions, while atthe same time providing a simple and effectivecorresponding adjustment of-the wheels of the sweeper which beardirectly on the brush pulley, and thus transmitting the power in themost simpleand effective manner at all adjustments of the brush, theoperation of the sweeper is considerably improved while the simplicityof construction with a small number of different parts to be assembled,make the cost of construction small.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent is:

1. In acarpet sweeper, thSE'combina-tiOn' with a casing, wheels, andarusli rotated through engagement with said wheels, of a mounting forsaid brush having a vertical slot. and a spindle for said brush bearingin and held against horizontal displacement by the sides of saidvertical slot, and a lever with a slot extending atan angle to saidvertical slot in the mounting and receiving said spindle to hold itagainst vertical movement in said vertical slot, or to move said spindlevertically insaid vertical slot, the sides of the slot in the lever andthe sides of the vertical slot in the mounting, within the regionwhere-said slots are adjacent, formvertical slot, and a spindle on saidbrush vertically adjustable in said slot and rotatable t herein,-of alever with a slot extending direct contact with the peripheries of said.wheels, a mounting for said brush having a at an angle to the verticalslotin the mountin and receiving said spindle, whereby the spindle isretained in the vertical slot and is adjusted up and down therein, thelower end of the vertical slot being open and-the lower end of the slotin the lever being open and said open end of the slot-in the leverrbeingadapted to coincide with the open end oi the vertical slot to allow thebrush to be re; moved from the sweeper, substantially ms specified.
